About
睡 is a phono-semantic compound with the eye radical 目 (mù) on the left, linking it to actions or states involving the eyes, and the phonetic component 垂 (chuí) on the right, meaning "to hang down". This structure visually represents heavy eyelids drooping as a person grows drowsy. Originally, the character specifically described nodding off from fatigue while seated. Over time, its meaning broadened to encompass the general state of sleeping or resting in any position, replacing older vocabulary for sleep.
